RADIUS Screen
8.1 Overview
This chapter describes how you can use the
Wireless > RADIUS
screen.
Remote Authentication Dial In User Service (RADIUS) is a protocol that can be used to manage user
access to large networks. It is based on a client-server model that supports authentication,
authorization and accounting. The access point is the client and the server is the RADIUS server.
Figure 39
RADIUS Server Setup
In the figure above, wireless clients
A
and
B
are trying to access the Internet via the NWA. The
NWA in turn queries the RADIUS server if the identity of clients A and U are allowed access to the
Internet. In this scenario, only client
U
’s identity is verified by the RADIUS server and allowed
access to the Internet.
8.2 What You Can Do in this Chapter
Use the
Security > RADIUS
screen if you want to authenticate wireless users using
a RADIUS
Server and/or Accounting Server (see
).
8.3 What You Need to Know
The RADIUS server handles the following tasks:
•
Authentication
which determines the identity of the users.
•
Authorization
which determines the network services available to authenticated users once
they are connected to the network.
•
Accounting
which keeps track of the client’s network activity.
